1080p (Full HD) at 120 fps with H.265 (HEVC): What You Need to Know
Planning to record or stream 1080p (Full HD) footage at 120 fps with H.265 (HEVC)? Knowing the exact file size and bitrate before you start saves both time and storage headaches.
Full HD at 1080p is the most widely adopted resolution for online video. It strikes the ideal balance between visual clarity and manageable file sizes, making it the default for platforms like YouTube, Twitch, and Vimeo. This resolution is particularly favored by corporate video producers and online educators.
Recording at 120fps is primarily used for creating smooth slow-motion effects. When played back at 30fps, you get a beautiful 4× slow-motion effect that reveals details invisible to the naked eye.
The H.265 (HEVC) codec offers approximately 40% better compression than H.264 at equivalent visual quality. HEVC cuts file sizes by nearly half compared to H.264, making it the go-to codec for 4K workflows. Hardware decoding support is now widespread on modern GPUs, smartphones, and smart TVs.
With these settings, a 10-minute clip weighs approximately 1.35 GB, while a full hour reaches 8.10 GB. You will need a minimum upload speed of 29 Mbps for reliable streaming. The total video bitrate for this configuration is 19.2 Mbps.
